This is NAS Expansion board with which you can build your own NAS (Network Attached Storage) device. Connect a hard drive or SSD, plug in an Ethernet cable, and use a Linux-based operating system to set up a home media server, data backup system, or general purpose file server.

It is really designed to be a cheap, low-power device for headless applications. But now there’s a way to make the little device into more of a fully functional Pc or at least a more capable file server.

Just plug the little computer into the expansion board and you get support for SATA and mSATA storage devices, two additional USB 2.0 ports, a 3.5mm audio jack and composite video output.

This NAS Expansion Board also has a microphone and IR server.

The video output could make it easier to set up the system, but you could also theoretically use this tiny little low-power computer as an inexpensive media player.
